The UPR-270 Air features best value for wobble and flatness and one can reach high accuracy because of high-precision air bearing. All rotation stages UPR-270 AIR are directly driven by a torque motor ...

This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor ...

The leading and longest established online Process Engineering publication serving the Process Manufacturing Industries ...

Position encoders are sensors that, when used in industrial settings, produce critical motor information such as speed and position. The encoder delivers data for display or data that may serve as ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

PI and PI miCos provide a large variety of rotary precision positioning stages with a number of different motor and drive options. Standard and vacuum compatible UHV versions are available. Options ...

It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...

This application note demonstrates how to read data from the two-channel output of an incremental rotary encoder. Data from these two channels are based on the Gray Encoding System and can be used to ...

Gearless drives, also known as direct drives, are used in the elevator technology for their high torque at low rotation frequencies and their smooth and silent operation. Gearless drives, also known ...

PI, a global leader in precision motion control and air bearing motion systems, offers the A-688 rotary stage, an advanced motorized, air-bearing based rotation stage, engineered for nanometer-scale ...
